I was more or less emulating the amd64 profile, so i figure that was the
right way to go. Is there anything else i should be looking for? I
carried this over from the old sparc profile for sparc32.

FEATURES="-multilib-strict"
MULTILIB_STRICT_DIRS="/lib32 /usr/lib32 /usr/kde/*/lib32 /usr/qt/*/lib32
/usr/X11R6/lib32"

That's seems somewhat dirty to me, but i carried it over because it worked.
